* Competently discuss Article 5: "Site Characterization in Densely
Fractured Dolomite: Comparison of Methodsransmissivity Variations in
Mudstones", by Maureen Muldoon and Ken R. Bradbury. (Ground
Water, Vol. 43, No. 6, p.
863-876.) Discussion leader: Paul.
* Explain what the purpose of a pumping test is, and tell what data are
collected in the field during such a test.
* Given a value of the parameter "u" for a pumping test, calculate the
corresponding value of the well function W(u).
* Given a value of the parameter "u" for a pumping test, use the well
function table in the textbook to find the corresponding value of W(u).
* Plot a graph of W(u) vs. 1/u (the reverse type curve) for Theis
* Plot a graph of field data from a pumping test (drawdown vs. time)
and use the curve-matching procedure to find transmissivity and
